The 55 points were the most scored in the NFL this season and the most ever scored against the Steelers.

Chiefs 23, Bills 13: Sean Smith returned an interception 100 yards for a touchdown, and Tamba Hali scored on an 11-yard fumble return for visiting Kansas City (9-0).

The Chiefs gave up a season-worst 470 yards to a Buffalo (3-6) offense that was led by rookie Jeff Tuel, making his first career start. Tuel completed 18 of 39 passes for 229 yards, including a 59-yard touchdown to Marquise Goodwin.

Jets 26, Saints 20: Nick Folk remained perfect this season by kicking four field goals, Rex Ryan’s defense limited Drew Brees and the high-scoring Saints to six points in the second half, and host New York (5-4) edged New Orleans (6-2).

Folk is 23 of 23 on field goals and 14 of 14 on extra points.

Panthers 34, Falcons 10: Cam Newton threw for one touchdown and ran for another to overcome a shaky start, the defense intercepted Matt Ryan three times, and host Carolina (5-3) beat Atlanta (2-6) for its fourth straight victory.

Newton had two first-half interceptions and regularly overthrew his receivers on deep passes. He bounced back to throw for 249 yards, including a 14-yard touchdown to tight end Greg Olsen.

Redskins 30, Chargers 24, OT: Darrel Young scored three times, including a 4-yard run in overtime that gave host Washington (3-5) a win over San Diego (4-4).

Young stormed his way into the end zone 6:01 into the extra period, with the Redskins scoring on their first drive after winning the coin toss at the end of regulation.

Titans 28, Rams 21: Chris Johnson ran for 150 yards and two touchdowns, and visiting Tennessee (4-4) got the best of St. Louis (3-6) and Jeff Fisher, who coached the Titans for 16 seasons.

Johnson’s 19-yard scoring run snapped a tie with 2:54 to go. It came one play after Jurrell Casey sacked and stripped the ball from Rams quarterback Kellen Clemens and Derrick Morgan recovered.
